Design and characterization of the 600 V IGBT with monolithic over-voltage protection

PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002
A 600 V IGBT with a monolithic overvoltage protection circuit has been developed to provide protection against overvoltage stress. The device operates under normal operating conditions just like a conventional IGBT but is able to sustain much higher avalanche energy under the abnormal operating condition of voltage overshoot.

An Over Voltage Protection Circuit for Series Regulator Power Supplies

IETE Journal of Education, 1975
AbstractAn over voltage protection circuit that protects the load from over voltages, in case of series transistor failure in a series regulator is discussed here. If the series transistor gets open between collector and emitter terminals, output becomes zero. In case of a short this circuit comes into action and makes the output voltage fall to zero.

Design of Over-Voltage Protection in Class-E Push-Pull Converter

2025 Energy Conversion Congress & Expo Europe (ECCE Europe)
This paper presents the design and implementation of a voltage clamp protection circuit for a high-frequency Class E push-pull resonant converter, addressing over-voltage surges caused by gating signal malfunctions. The study investigates the impact of gate propagation delay on over-voltage spikes and proposes an optimized RCD clamp circuit to ...

A simple over-voltage protection device for a low-frequency power amplifier

Journal of Scientific Instruments, 1967
A 120 w amplifier is used as a source of electrical power at or near mains frequency. A simple device is described, incorporating a Mullard lamp-photocell unit type ORP39, which gives limited but acceptable protection to the amplifier load from over-voltages, but has no effect on amplifier gain at output voltages equal to or less than the nominal ...
